Fifteen of the top 20 fastest-growing major airports in the world by passenger numbers are located in Asia.

Phnom Penh International Airport has topped the list of fastest-growing major airports on earth, a new study by Routesonline has found, after increasing passengers by more than 38% in the last calendar year.

Phnom Penh was one of 15 airports located in Asia to feature in the top 20. Five of those were in China and a further five in India, highlighting the growing dominance of the two countries as aviation powerhouses.

At number two in the list of fastest-growing airports is Quanzhou Jinjiang International, an airport serving the city of Quanzhou in the south-eastern Chinese province of Fujian. Its year-on-year growth was 31.9% to more than 8.1 million passengers, driven by the expansion of Shenzhen Airlines and Xiamen Airlines.

New routes included Shenzhen Airlines’ services to Chongqing and Zhuhai, and Xiamen Airlines’ flights to Haikou and Kaohsiung.

Jinjiang is the first of ten airports located in China and India to feature in the top 20 list. Other high-ranking Chinese airports are Yantai (6th), Nanchang (12th), Shantou (13th) and Da Nang (19th).

According to the latest figures from the International Air Transport Association (IATA), China will displace the US as the world’s largest aviation market (defined as traffic to, from and within the country) in the mid-2020s, while India will surpass the UK to take third place around 2024.
